Oakley Vault takes up to 50% off select men's and women's T-shirts, with prices starting at $9.99. (Prices are as marked on the product page.) That's the best discount we've seen on T-shirts from Oakley Vault since August, when they took up to 80% off. Shipping adds $6.58, or spend $50 or more to qualify for free shipping.

A best bet is the Oakley Vault Men's Frequency T-Shirt in four colors (Fluid Blue pictured) for $24.99 plus $6.58 for shipping. That's $13 off and the lowest total price we could find. It's available in sizes from S to XL, although not in all size/color combinations.
